> With https://issues.apache.org/jira/browse/AMQ-2400 we introduced vmCursor and memory
limit for all topics by default. While this improved throughput in high-volume topic scenarios
it can cause a single slow consumer block the producer and affect all other producers.
> The proposition is to use pendingMessageLimitStrategy by default and limit the number
of messages we're retaining by default for consumer as a strategy for dealing with slow consumers
(instead of blocking)
> We also need to add more documentation explaining all aspects of these settings and their
consequences.
